Organisms affect soil, in terms of aeration, drainage, fertility, moisture, nutrientavailability, and structure. For organisms such as burrowing moles and voles, and tunneling earthworms, open up passageways through soil. These passageways provide channels for air, moisture, and nutrients; options for drainage; and transport for other members of the soil food web. Soil dwelling organisms also die and decompose. By their death and decay, they add to the organic matter in soil. Organic matter improves drainage, fertility, and structure. And organisms such as ground beetles and earthworms feed on other organisms. The processing of the digestive system and the elimination make nutrients available that otherwise are present but inaccessible. For example, nitrogen fixing bacteria need to be digested, processed, and eliminated as the waste products of their predators in order for their nitrogen to be in soluble form and therefore available for use within the soil. And also organisms such as bacteria and fungi improve soil structure by their glue and their threads, respectively. For bacterial glue and fungal threads help soil to form into aggregates. Between and among the aggregates can be formed air and water pore spaces.

Describe how soil organisms affect the soil?
it makes it easier or more difficult for plants to grow by affecting the availability of things they need.
How do living organisms help soil?
Living organisms provide nutrients for the soil.
How do soil organisms affect the soil?
Soil organisms play an essential role in the breakdown of organic matter and other complex molecules. These activities are also linked to processes that lead to the aggregation of soil particles into a friable soil structure that is beneficial for the growth of plants. The inter-connected activities of soil organisms improve soil stability and underpin nutrient cycling on a global scale. Part 2 covers the chemical and physical processes associated with the activity of soil organisms including: (i) in nutrient cycling; (ii) in degrading complex molecules such as pesticides and chemicals that may contaminate the environment, and (iii) in soil stabilisation and other soil physical processes.Resource: SoilHealth .com
How do soil organisms improve the soil?
Organisms and insects help to keep soil healthy. They help break down harmful elements and excrete substances to improve the soil.
What is the 5 factors that affect runoff?
I think they are Parent material, Relief, Organisms, Climate, and Time.
How does soil fertility affect crop production?
- soil pH -soil organisms -soil structure -soil texture -adsorption complex -
Can the different types of soil affect the organisms in that ecosystem?
biodiversity
What factors that determine the soil pH?
The factors which affect soil pH levels are the amount of rainfall, the amount of plants and the number of soil organisms.
How does soil affect the environment?
Living "things" or Organisms can affect the characteristics of soil in many ways. Geographical location, pollution, the amount of living organisms in the soil, as well as any dead organisms in the soil will change its characteristics and development.

How do soil organisms affect the nutrients available to plants?
Soil organisms affect the nutrients available to plants. In a hard rocky soil,absorption of water and oxygen is minimal. In a fertile soil, availability of water and oxygen is maximum which help in proper growth of plants. Even where the sun rays do not reach the soil adequately specially in dense forest, the soil organism is not conducive to nutrients available for palnts' growth.
How does soil composition affect the number and types of organisms and environment can support?
I dont know :d

How indigo cultivation affect the soil?
indigo cultivation affects the soil; by soil erosion ,taking away the top soil making the soil more rougher and making the soil not good for cultivation and is affected by micro organisms
List some soil organisms?
soil organisms
What factors affect the thickness of the horizons and the composition of the soil?
I think this is the answer: Some soil organisms mix the soil and make spaces in it for air and water. Other soil organisms make humus, The material that makes soil fertile.
